Also known as: RX.Helix, Merkel Helix

Overview

The Merkel RX Helix is a German straight-pull bolt-action hunting rifle introduced in 2010. Its defining feature is a 1:2 transmission gearing that halves the linear bolt-handle travel, allowing exceptionally fast follow-up shots while the seven-lug rotary bolt head cycles entirely within a fully enclosed action housing. The rifle offers tool-free takedown and interchangeable barrels, letting a single receiver be rechambered across calibers from .222 Remington up to .300 Winchester Magnum.

Background

The Helix straight-pull mechanism originated not with Merkel but with Sheikh Hamed of the Abu Dhabi royal family, whose concept for a short-throw geared bolt was engineered into a production rifle by the Suhl-based maker.
